SatEvo prediction for the final orbits:

Note: The current elset shows this running 9 seconds late against
the SatEvo prediction I posted here yesterday. I place decay on the
approach to a southbound equator crossing at 22:44 near 85 deg W. That
orbit takes it over SE over the USA and Mexico from N California at
22:30 UTC to Mexico City at 22:38.
